DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outboard motor in which a plurality of intake pipes are vertically arranged on the side of an engine body.

[0002]

2. Description of the Related Art Conventionally, a battery cable terminal supported by an engine body has been used to connect a battery cable to an outboard motor. This terminal is attached via a bracket near the engine body when assembling the outboard motor, and connects the outboard motor end of the battery cable to the power supply end of the starter motor and other electrical components. I have. This terminal is arranged near the engine body in order to prevent the screw for fixing the cable from being loosened by vibration of the engine.

[0003] The battery cable has an end on the hull side leading out of the front end of the outboard motor, and is connected to a battery in the hull. The battery cable is assembled to the outboard motor in advance when the outboard motor is manufactured, and the battery side end is connected to the battery after the outboard motor is mounted on the hull.

[0004]

In recent years, the hull on which an outboard motor is mounted has been diversified, and the position and number of batteries have been different for each model. For this reason, the battery cable is pre-wired to the hull when the hull is manufactured, and the outboard motor side end of the battery cable is connected to the battery cable terminal of the outboard motor after the outboard motor is attached to the hull. .

However, in the conventional outboard motor, the battery cable terminal is arranged near the engine body, and is often located on the back side (engine body side) of members such as other auxiliary machines. Therefore, it was difficult to connect the battery cable after assembling the outboard motor (after attaching the outboard motor to the hull). That is, it is necessary to remove a blocking member to connect the battery cable.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to enable a battery cable to be easily attached to and detached from an outboard motor in a completed state.

[0007]

In order to achieve this object, an outboard motor according to the present invention comprises a plurality of battery cable terminals for connecting a distal end portion of a battery cable arranged vertically in a lateral direction of an engine body. The battery cable is disposed at a position exposed to the outside through a space formed around the provided intake pipe, and a battery cable routed through the space is detachably connected to the terminal.

According to the present invention, the outboard motor-side end of the battery cable is shielded by other members even when the outboard motor is completed, while adopting a structure in which the battery cable terminal is disposed near the engine body. It can be attached to and detached from the terminal without the need.

An outboard motor according to the invention described in claim 2 is:
In the outboard motor according to the first aspect of the present invention, the battery cable terminal is attached to the engine body via a bracket. According to the present invention, the battery cable terminal can be arranged close to the engine body, and the amplitude of engine vibration transmitted to the fixing screw for connecting the cable to the terminal can be minimized. Can be.
